Fair would be just deleting the videos like GG suggested, no need to penalise as well considering the age of the videos and the fact it wasn't done intentionally for any monetary gain.

15 infractions in one hit!! Fucking ridiculous.
Is LL outsourcing the mod jobs to sweat shops in Bangladesh or some other shithole with small headed numpties.
